Question 72

The Qutab Minar casts a shadow 150 m long at the same time when the Vikas Minar casts a shadow 120 m long on the ground. If the height of the Vikas Minar is 80 m, find the height of the Qutab Minar.

Solution

Ratio of their heights = Ratio of length of shadow (since angle will be same)

Let height of Qutab Minar = $$h$$ m

=> $$\frac{h}{80}=\frac{150}{120}$$

=> $$h=\frac{150}{1.5}=100$$ m

=> Ans - (A)
